A misfiring engine will cause, low gas mileage, low power output, increased emissions and possible internal engine damage if left untreated. Typically an engine misfire under load, will be a problem with the ignition system, while low engine speed problems will be a vacuum, fuel management or compression issue.
Coral colonies grow through a form of asexual reproduction known as budding, in which polyps divide themselves to form new polyps . Corals can also reproduce sexually by spawning, which in Platygyra daedalea involves the release of gametes into the water, for external fertilisation. Platygyra daedalea is hermaphroditic, meaning that each polyp produces both eggs and sperm.
The four main cnidarian groups (or classes) are Anthozoa (anemones, corals, etc.), Scyphozoa (jellyfish), Staurozoa (stalked jellyfish), Cubozoa (box jellies), Hydrozoa (Obelia, Portuguese Man o' War, Aequorea, etc.), and Polypodiozoa, which includes a single species, Polypodium hydriforme, a small parasite.ike other members of this phyla, corals can reproduce either asexually, by budding, or sexually, by releasing sperm into the water. These organisms have two major body forms: the polyp, which is a stalk with cnidocytes at its top, or the medusa, which is the iconic shape of the jellyfish.
